Definition & Meaning of "pin nailer"

What is a "pin nailer"?

A pin nailer is a small, lightweight tool used for driving very thin, short nails, known as pin nails, into wood or other materials. It is commonly used in woodworking, trim work, and furniture making where small, discreet nails are needed to hold pieces together without leaving large holes. The pin nails are so small that they often do not require filling, leaving a clean, smooth surface. Pin nailers are especially useful for tasks that need precise, delicate fastening without damaging the material.
